Abstract
Toxic effects of phenol on the activated sludge process were evaluated by determining the changes in DO in a laboratory-scale unit. A series of phenol concentration significantly affected the activated sludge. The effect of phenol was variable depending on its concentration. With the increase of phenol concentration, oxygen uptake rate (OUR) decreased. The inhibitory concentration that reduced the sludges specific oxygen uptake 50% from its maximum rate was determined (IC50).
